Science Lesson Plan: Decomposers

Grade Level: 5
Duration: 30 minutes
Subject: Science
Topic: Decomposers

---

Objective

By the end of this lesson, students will be able to:

• Define decomposers and explain their role in the ecosystem.
• Identify common types of decomposers and their characteristics.
• Understand the importance of decomposers in nutrient cycling.

---

Materials Needed

• Chart paper and markers
• Pictures or samples of decomposers (fungi, bacteria, earthworms)
• Decomposers worksheet
• Whiteboard and dry-erase markers

---

Introduction (5 minutes)

1. Engage the Students:

   • Start with a question: "What happens to leaves that fall from trees or food scraps we throw away?"
   • Allow students to share their ideas and experiences related to decay and recycling in nature.

2. Introduce the Topic:

   • Explain that today, we will learn about decomposers - the organisms that help break down dead material and recycle nutrients back into the soil.

---

Direct Instruction (10 minutes)

1. Define Decomposers:

   • Present the definition of decomposers: "Decomposers are organisms that break down dead and decaying organic matter."

2. Role in Ecosystem:

   • Explain the role of decomposers in the ecosystem:
     • They help recycle nutrients, ensuring that soil remains fertile.
     • They contribute to the food web by providing nutrients for plants.

3. Types of Decomposers:

   • Discuss common types of decomposers:
     • Bacteria: Microscopic organisms that break down organic material.
     • Fungi: Mushrooms and mold that decompose organic matter.
     • Earthworms: Consume dead plant and animal material, improving soil structure.

4. Importance:

   • Emphasize how decomposers are crucial for sustaining life on Earth by enabling nutrient cycling.

---

Guided Practice (5 minutes)

• Activity: Decomposer Match-Up
  • Hand out pictures of different decomposers.
  • On a chart paper, create two columns: one for types of decomposers and the other for their roles.
  • Have students work in pairs to match pictures with descriptions or roles of each decomposer.

---

Independent Practice (5 minutes)

• Worksheet Activity:
  • Distribute the decomposers worksheet that includes:
    • Multiple-choice questions regarding the types and roles of decomposers.
    • A section for students to draw or describe their favorite decomposer.

---

Closing (5 minutes)

1. Review Key Concepts:

   • Ask students to share one new thing they learned about decomposers.
   • Summarize the lesson by reiterating the importance of decomposers in the natural world.

2. Exit Ticket:

   • As students leave, have them write down one thing they can do to promote healthy decomposing in their environment (e.g., composting).

---

Assessment

Students will be assessed based on their participation during discussions, the accuracy of their answers on the worksheet, and their ability to engage in the match-up activity.

---

Differentiation

• For students needing extra support, provide simplified texts or direct assistance during the match-up activity.
• On the other hand, for advanced learners, assign them to research a specific decomposer and present interesting facts to the class in a following lesson.

---

By implementing this lesson, students will gain a firm understanding of decomposers and their vital role in the ecosystem, preparing them for future scientific inquiries related to ecology and environmental science.
